.The primary object of the invention is to provide afpencil Sharpener ofthe portable i type comprising a tubular member providedv witha pencilsharpening blade that carries Va clasp extension whereby the pencilSharpener maybe carried upon'either end of the'pencil Withthe claspmember engageable with the usual `annular beads ,onsthe ferrule of thepencil or with-a side oi the pencil adjacent the pointed sharpened end.'l

A further obj ect of the invention is to pro# vide a portable pencilSharpener of the -foregoing character in the form of a tubular mem# berhaving-a/longitudinal slot in one side forV the mounting of-a combinedsharpening blade and clasp extending into the bore of the tubularmember, the interior body portion of the tubular member-having a pocketthereinA to receive the sharpened pointed end of' a pencil withthepclas'p engageablerwith a sideoffthe pencil adjacent the pointed fendvfor, theiprotection of the sharpened'pencil when out of '25 use andsaid clasp being `retained upon Ythe opposite end of the pencil when thelatter is in use by means of the 'clasp resiliently. engaging the usualannular beads on the ferrule ofthepencihV Y.' Y Gf 'i 3 With the aboveand other objects in view that will become apparent vas the nature ofthe invention is better understood, the same consists in the novel form,combination'and arrangement of parts hereinater morefully described,shownk in the accompanying drawing andclaimed. K "l .i In the drawing vA f F`gure 1 is a side elevational view of the pencil vSharpener mountedupon thel eraser carrying end of alpencil; .l l Figure 2Y is a sideelevational vewxof the Sharpener with the pointed end of the pencilinsertedtherein for a sharpening operation; Figure is an end elevationalview of the VSharpener disclosing the sharpening. blade exp Applicationinegi August i7, 1932. seriain'o, 629261.

Figure v 9 is a 'longitudinal' sectional vView, similar to Figures 5 and6, showing the point#` ed end of a pencil'confined .within the sharpenerby'l meansof the clasp;`

{Referring more indetail to the accom- Y* panying drawing, there isillustrated a pencil SharpenerV constructed of any suitablematerialdesired, such as metal,hard rubber or the like, the pencil Sharpener l0being of cylindrical form and longitudinally corrugated as at 11 to`i'acilitate vsharpening rotation thereof when mounted uponthepointedend ofa pencil. kThe `cylindricalmember of the Y pencil `sharpener 10includes' the pencil sharp# ening Vend 12 and the pencil carrying end13.v

The pencil sharpening end 12;'i`s'provided .with a canted conicalrecess'14 having one side thereof substantially parallel-with theadjacent sideV of; the cylindricalbody lof the Sharpener whilethe'iother' siderin'clinedVv to provide an interior-body portion15 ofin'- K creased; diameter providingua transversely ex= 'u tendingcrossshoulder 16 at the inner end of the socket 17 at the pencilcarrying end 13 of the sharpener.

A longitudinally extending slot 18 is formed in the side of thecylindrical member of the Sharpener and opens into the conical recess 14and pocket 17 at the side of the sharpener` spaced from the increasedbody portion 15 for the mounting of a combined pencil sharpening bladeand pencil gripping clasp. The slot 18 extends completely through thepencil sharpening end 12 of the device and terminates inwardly of thepencil carrying end 18, being closed by the bridge piece 19,. One ofthewallso the slot`18 is tangentially V'disposedwith respect tothecylindrical memberY of the Sharpener orthe' mounting of a pencilsharpening blade 2Qretained in position on the said Walllo'y means ofthe screw 21 with theA sharpened edge `oi' the blade extending into theconical recess 14 as. clearlyillustrated in FiguresV 3 and 7. The blade20 extends lsubstantially the complete length of the conicalrecess 14and at its inner end carries a laterally` offset clasp extension 22normallyA disposed within the pocket 17 at the pencil carrying end 13 ofthe device withan oifset shoulder 28 adjacent `the ree end of the clasp22. c Y.

When the pencil `Sharpener is out of; use, the same may be carried uponthe errule carrying end ofthe pencil P. as.shown in Figures 1 and 5 withthe shoulder 23 of the clasp 22 resiliently engaged with an annular beadB carried by thepencil ferrule F.V To sharpen the pencil P,- thekpencilis removed from the pocket 17 and the sharpening or pointed end AEis insertedin the conical recess 14, rotation of the Sharpener uponthepointed end'of the pencil facilitated by the corrugations 14CA producinga sharpened pointon the pencil as Vshown in Figure 6. The Sharpener maybe carried by the pencil as shown in Figures 1 and 5 when thepencil isbeing used and when vthe pencil is out of service,"the pointed orsharpenedend VE thereofis'protected by the mounting of a Sharpener onthe pointed end of the pencil as illustrated in Figure 9.

The cross wall 16 of the bodyl portion 15 of the sharpeneris providedwith a conical so cket 24 to receive the pointed end of the pencil withthe clasp 22 engaged witha side of the pencil as illustrated in Figure 9forV retaining the sharpening device on the pencil. Y

--While there is herein shown and described the preferred embodimentofthe invention,

it is nevertheless to be understood that minor ,changes may be madetherein without des parting from the spirit and scope of the'inventionas claimed. f
